The Goodman B1370154 Rollout Limit Switch is a genuine OEM flame rollout safety control engineered for GMPN040-3 gas furnaces. This manual-reset switch opens the ignition circuit if flame rolls out of the burner box, shutting down the furnace to prevent overheating, heat exchanger damage, and unsafe combustion conditions. It is a critical, code-required safety device and one of the most common causes of a furnace that locks out on ignition.

Type: Manual-reset flame rollout switch
Trip Temperature: 350°F (open on rise)

OEM vs. Generic

This is a factory-authorized Goodman OEM component, calibrated to the exact 350°F trip point specified for your furnace's burner assembly. Generic aftermarket rollout switches may use looser tolerances or incorrect trip temperatures that either nuisance-trip or fail to protect the unit. For a safety-critical control, we recommend the OEM part for guaranteed fit and calibration.

Installation Difficulty

Easy (2/5). Two mounting screws and a pair of quick-connect spade terminals. Always disconnect power before servicing. If the replacement switch trips again immediately, investigate the underlying cause (blocked flue, cracked heat exchanger, or dirty burners) before repeated resets.
